We know that http://en.wikipedia.org/wiki/Pyrolytic_carbon" [Broken] layers will have an omni directional cleavage and possibly an omni directional Diamagnetic field. Also, could a http://www.ebteccorp.com/lasercut.html" [Broken] cut such a thin sheet of Pyrolytic carbon to transparent thickness, If not then say 5 microns or less? Note: The most strongly diamagnetic material is Bismuth χ = −166×10−6, although pyrolitic graphite may have a susceptibility of χ = −400×10−6 in one plane. If pyrolitic graphite can be made Diamagnetic omni directional by the above method it will be the strongest Diamagnetic substance at room temperature and Bismuth will be history. Also, Does anybody know of any company that gives free samples of Diamagnetic pyrolitic graphite for product evaluation, I intend to carry out the above experiment to see if the omni directional diamagnetic field exists. Another question is, does Diamagnetic Graphite increase in Diamagnetism with Tc?
